BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a fencing system, and more particularly, theinvention relates to a fence rail holder for connection to conventionalmetal fence posts.

2. Brief Description of the Related Art

There are many different fencing options for fencing horses and otheranimals such as wood, PVC, high-tensile wire, barbed wire, wire mesh,metal pipe, and others. Each of these fencing materials has differentadvantages and disadvantages in the areas of strength, visibility,aesthetics, and maintenance.

Wooden plank or post and rail fencing is both sturdy and attractive.Wood fencing is also quite visible to horses which discourages them fromcrashing into the fence. However, wood fencing requires high maintenancein painting and replacing rotten wooden fence posts and rails. Woodenfencing is also rather costly.

Wire fencing including barbed wire and wire mesh fencing is easy toinstall and uses a common inexpensive metal “T” post system forsupporting the fencing. However, the metal T-posts of this type offencing are narrow and the wire is thin making the fence very difficultfor animals to see particularly in poor light.

PVC fencing has been used as an alternative to wooden fencing andprovides the superior aesthetics of a conventional wooden fence withoutthe associated maintenance. However, the new PVC fencing systems arerelatively expensive. In addition, animals may lean or rub against thePVC fencing causing it to crack in cold weather.

Accordingly, it would be desirable to provide a fencing system havingthe visibility advantages of a wooden or PVC fence with the costadvantages of a wire mesh or barbed wire fence.

It would also be desirable to provide a system for easily mounting anelectric wire on a PVC fence to prevent animals from leaning or rubbingon the fence.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The fence rail holder 10 according to the present invention provides thevisibility of a wooden or PVC fence at a lower cost because it enables aPVC fence rail to be connected to the inexpensive metal posts commonlyused to install barbed wire and wire mesh fences. The fencing system ofthe present invention also provides a way to attach an electric fence orhot wire to PVC fencing.

As shown in FIGS. 1-4, the fence rail holder 10 includes a hollow bodywhich defines rectangular openings 12 at opposite sides, configured toreceive a commonly available fence rail 100. The fence rails 100 areeasily visible and the cross-sectional area of each rail is in the rangeof about ½ by about 1 inch, to about 5 by about 8 inches. The fencerails may also be square in cross section. In one embodiment, the PVCfence rail is about 1½ by about 5½ inches.

Two clips 16, 18 including a fixed upper clip 16 and a slidable lowerclip 18 are positioned on a rear surface of the fence rail holder 10, asshown in FIGS. 2-4. These clips 16, 18 have somewhat U-shaped portionswhich are substantially the same size and shape and are configured to bereceived on the conventional “T” shaped fence posts. The clips 16, 18have a configuration which allows the fence rail holder 10 to be easilysnapped onto the “T” posts and to be removed from the posts by pressingon the elongated lever end 14 of the clip. Attaching the fence railholder 10 to a “T” post allows the addition of a very visible, white orother colored PVC, or other rail to a conventional barbed wire or wiremesh fence. The PVC rail may be placed along the top of the fence inplace of or in addition to a top strand of barbed wire.

As illustrated in FIGS. 2 and 4, each clip has a mounting portion 46which can be received in an opening 26 in the rear surface of the fencerail holder 10. In one embodiment, the mounting portion 46 has a groove48 disposed about an edge of the mounting portion. When the clip 16, 18is inserted in the fence rail holder 10, the groove 48 engages the sidesurfaces of the opening 26. The mounting portion 46 has an optionallocking mechanism 62 which secures the clips 16, 18 in place wheninserted in the fence rail holder 10. The locking mechanism 62 includesa tail which extends downward from the clips 16, 18 and snaps into theopening 26 and prevents clips from sliding out of the opening.

The conventional metal “T” posts 110 have a plurality of protrusions112, shown in FIG. 1, along a front face which prevent the wire 114 fromslipping along the post. Since there is no industry standard for thesemetal fence posts 110, the spacing between the protrusions 112 varieswidely between manufacturers. The slidable lower clip 18 which slides inthe elongated lower opening 26 allows the fence rail holder 10 to bemounted on posts from different manufacturers. Generally, the upper clip16 will be snapped onto the fence post between the top two protrusions112 and the lower clip 18 will be adjusted by sliding the clipvertically in the lower opening 26 in the fence rail holder 10 so thatthe lower clip can be received on the fence post without obstructionfrom the protrusions.

The fence rail holder 10 is preferably constructed of plastic, such asPVC, and includes a wire support member 20 on a front surface whichallows the mounting of an electric wire 116, barbed wire, electric tape,electric rope, or other wire along a front face of the fence rails 100.The wire support member 20 is fabricated from an electrically insulatingmaterial and may be integral with or separate from the fence rail holder10. Examples of wire support members will be described in further detailbelow with respect to FIGS. 5-9.

The fence rails 100 are inserted into the openings 12 on either side ofthe fence rail holder 10 and may be held in place by tangs on the railor by other fasteners. For example, the fence rail holder 10 may beprovided with a plurality of holes 24 in the front or rear surface.After the fence rails are inserted into the openings 12 in the sides ofthe fence rail holder 10, a hole may be drilled in the fence railthrough the holes 24 in the fence rail holder 10 and a pin 64 or tab isinserted into the hole. The fence rail 100 is prevented from beingremoved from the fence rail holder 10 by the ends of the pin 64. Thisprovides an easy attachment system for attaching the fence rails 100 tothe fence rail holder 10 in a removable manner which prevents the fencerails from falling out of the fence rail holder if the posts shift. Theattachment system also allows some amount of give between the fence railholder 10 and the rails 100.

FIGS. 5-9 illustrate two embodiments of wire support members 20A, 20Bhaving two different connections for connecting to a PVC fence post,rail, or to the fence rail holder 10.

FIGS. 5 and 6 illustrate one example of a wire support member 20A havingtwo fingers 38, 40 for receiving and supporting a hot wire or otherwire. The fingers 38, 40 are generally U-shaped and have a wirereceiving slot 42. One slot 42 of one of the fingers 38 opens upward andthe other slot of the other finger 40 opens downward so that one finger38 limits vertical upward movement of a wire (not shown) resting in theslot 42 while the other finger 40 limits vertical downward movement ofthe wire.

FIG. 6 illustrates a rear view of the first embodiment of the wiresupport member 20A. According to this embodiment, the wire supportmember 20A is provided with a circular protruding shaft 68 having twotabs 70 or key members which extend from the shaft for locking themember into place. In use, an opening is formed in the fence rail holder10 or other fencing member which is configured to receive the shaft 68and the tabs 70. The wire support member 20A is inserted into theopening and rotated 90 degrees to lock the member in place.

An alternative embodiment of a wire support member 20B, as shown inFIGS. 7-9, has a snap fit connection for quick mounting the member intoa fencing system. The snap fit connection includes a stem 44 having atapered or conical shaped rim 72. The stem 44 mounts the wire supportmember 20 on the fence rail holder 10. As shown in FIG. 8, the stem 44is provided with at least one longitudinal slot 50 which the slot allowsthe stem 44 to be compressed to a smaller diameter to snap into anopening in a fencing member. The opening in the fencing member has asmaller diameter than the rim 72 such that when the stem 44 is insertedin the opening, the stem and rim compress to create a close fit betweenthe fencing member and stem. FIG. 9 is a top view of a conventional PVCpost 120 and PVC rail 100 system having a circular opening 28 drilled inthe post for attaching the wire support member 20B in a snap fitarrangement.

In an alternative embodiment, the stem 44 comprises a plurality ofspring-contact fingers which form a hollow body. When inserting the stem44 in the opening, the spring-contact fingers deflect and allow the stemto pass through the opening. Examples of the attachment means forattaching the wire support member 20 to a fence member have beendescribed. Other examples of attachment means include but are notlimited to clamping, snap fitting mechanisms, turn-keys, lippedsurfaces, and welding.

FIGS. 10-12 show the construction of another embodiment of the fencingsystem having an adaptor 52 for mounting the wire support member 20B toa fence rail. The adaptor 52 is received on a fence rail and supportsthe wire support member 20. The adaptor 52 may be used when an ownerdoes not wish to drill holes directly into the PVC fence rails 100 orwhen it is desirable to offset the electric wire a distance from thefence rails. The adaptor is particularly useful when a spacing betweenadjacent “T” posts 110 becomes longer than a suggested 8 foot interval.The adaptor 52 clips on to the fence rail 100 so that a wire supportmember 20 can be installed mid span to ensure that the electric wiredoes not sag against the fence wire 114. The adaptor 52 includes abracket 60, which is adapted to be positioned around at least a portionof the fence rail 100, and a connector 58 supported by the bracket. Thebracket 60 may be provided with a roughened and/or tacky surface tofacilitate gripping the fence rail. The roughened surface enhances thefriction between the surfaces and may comprise any suitable means,including but not limited to grooves, ridges, ribs, or the like. Thebracket 60 may be adapted to be mounted on rectangular, circular, squarefence rails, or fence rails set at an angle. Further, the adaptor 52allows electric wire mounting on fence rails without drilling holes inthe fence rail.

The connector 58 forms a cavity 56 with an opening 54 for receiving thestem 44 of the wire support member 20B in a snap fit connection. Incombination, the fence rail holder 10 and the adaptor 52 allow thefencing system to support a wire at the fence posts and along fencerails. The connector 58 extends from the bracket 60 a distance such thata wire held by the wire support member 20 does not contact the fencepost, fence rail, or wire fencing.

The fence rail holder 10 according to the present invention may also beused with other types of fence posts such as round or square woodenposts. FIGS. 13-15 illustrate an alternative embodiment of a clip 30which is configured to allow the fence rail holder 10 to be attached toround or square fence posts. The clip 30 includes holes 32 which allowthe clip to be nailed to a round, square, or other shaped wooden fencepost or screwed or riveted to a square, round, or other shaped metalfence post. The clip 30 takes the place of the clips 16, 18 forsupporting the fence rail holder 10 on the post.

FIGS. 16-19 illustrate two embodiments of a fence post cap for fasteninga fence rail holder 10 to a top of a fence post. The fence post cap 80Aof FIGS. 16 and 17 has a D-shaped cross section, a domed top 82, and amounting portion 86 to be received in a top opening 26 of the fence railholder 10. An interior of the cap 80A includes two pairs of ribs 88 forcontacting the front and back of the T-post 110. The fence post cap 80Bof FIGS. 18 and 19 has a circular cross section. Other shaped fence postcaps may also be used.

The fence post caps 80A, 80B support the fence rail holder 10 at a topof the fence post. The caps 80A, 80B prevent animals from injuringthemselves on the tops of the fence posts. The caps also prevent animalsfrom being able to push the fence rail holder 10 down on the post 110.The fence post caps may be integral with the fence rail holder 10 orseparated as shown.

Several fence rail holders 10 may be used on a single post to form amulti-rail fence. The fence system of the present invention may be usedwith or without a wire mesh fence.

The fencing system according to the present invention provides theadvantages of easy installation, low cost, durability, and visibility.In addition, the fencing system helps to shield the dangerous exposedtop of the metal post. The fencing system also allows the incorporationof an electric wire or barbed wire onto the front face of the fence railholders and fence rails.

The wire support members 20 according to the present invention provide asimple low cost manner of attaching an electric wire to PVC sensingsystems. Animals tend to lose “respect” for vinyl fencing withoutelectric wire and cause damage to the fence by leaning, scratching,kicking, or reaching through the fence. The wire support members 20provide a way to attach an electric wire to the PVC fencing system.

While the invention has been described in detail with reference to thepreferred embodiments thereof, it will be apparent to one skilled in theart that various changes and modifications can be made and equivalentsemployed, without departing from the present invention.
